which statement regarding the selection of a hard drive is accurate This is a topic that many people are looking for. khurak.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, khurak.net would like to introduce to you Why Hard Drives Are Smaller Than Advertised? – ThioJoeTech. Following along are instructions in the video below:
“Guys today. I m going to explain something that i know i ve been on on your minds. If you ve ever gone and tried to buy a hard drive external or internal. You ll definitely notice when you go to the store.
And see the advertisement on the box. It ll say either something like 1 terabyte 500. Gigabytes and then when you go home and install it on your computer. If you re using windows.
You ll notice that the hard drives are significantly smaller than what is advertised on the box. A lot of people will say. This is false advertising or that the manufacturer is lying about the size of the hard drives. But this is actually not the case they are telling the truth it all comes down to units you see when you buy a hard drive.
The manufacturer will almost always display the size of the hard drive in gigabytes or terabytes now a gigabyte is 1000. Megabytes and a terabyte is 1000. Gigabytes however windows actually measures hard drive space in something called. Meby bytes and gibby bytes.
It does not display that it s using these units. It displays the gigabyte and megabyte unit..
Which leads to a lot of confusion. You almost definitely have not heard of these units. So i ll try to break it down you see. The megabyte unit is mb.
Capital. Mb and gigabytes. Is capital g. B.
But gibibyte. Is capital g. Lowercase. I capital b.
And maybe bytes is capital m. Lowercase. I capital b. So while windows is truly measuring in gigabytes and meby bytes.
It s displaying megabytes and gigabytes. So when you plug in your hard drive..
It s showing. The wrong units. If you plug in a terabyte hard drive it ll probably be about 931 gigabytes displayed in windows. Now that s not true.
It s actually 931 gibi bytes. Because a gibibyte is slightly larger than a gigabyte if you were to plug it into linux which measures in actual gigabytes you will see that the hard drive is. 1000 gigabytes you can do the math yourself a gibibyte is 107 four times the size of a gigabyte so if you divide a thousand by unit 107. 4.
You will get 931. Which is the size that windows displays it as now i m going to clear up some misconceptions about gigabytes and megabytes a lot of people seem to think there are 1024 megabytes in a. Gigabyte but there are actually 1024 maybe bytes in a gibibyte and there are in fact. 1000.
Megabytes in a gigabyte now this misconception comes from random access. Memory manufacturers. Ram. Manufacturers when they display on their box.
That they have 4 gigabytes of ram for example. You ll see that it says 4096 megabytes of ram..
Now they re actually measuring in gb bytes and maybe bytes again because there are 1024 megabytes in a gigabyte. But again they displayed as gigabytes and megabytes. They do this because most people are familiar with just using gigabytes and megabytes. They ve never even heard of gigabytes and megabytes now you re probably wondering where they came up with this unit.
Gibby. Bytes and megabytes. They re not a million or billion bytes like megabytes and. Gigabytes so why do they have this odd.
Unit 107. 4 gigabytes. Where do they come up with that it s actually pretty simple. You see giga the prefix means billion or 10.
To the 9th. So. A gigabyte is a billion bytes and likewise mega means millions. So that s a million bytes or 10 to the 6th.
But maybe and gabi bytes are a little bit different you see while megabytes and gigabytes are 10 to the 6th and 10 to the 9th bytes respectively. May be bytes and gibby bytes are binary multiples..
Which mean that there are 2 to the 20th bytes and 2 to the 30th bytes respectively. So for a memory. But you multiply 2 times itself 20 times and do the same thing for a gibibyte 30 times. Now as you can see when you do this you re not going to get a nice round number like a billion bytes.
You re going to get a strange number like specifically a meby byte is about 10. 4. Times. 10 to the 6th now this inconsistency is pretty much just for windows ever since.
Mac os version 106. They ve been reading file size in disk space as megabytes and linux does this as well. But windows still reads gigabytes and megabytes as gigabytes and megabytes. So i hope that was pretty clear.
If you have any questions leave a comment now hopefully when you go to and buy a hard drive you can understand where the sizes are coming from. And why it might be a little smaller depending on your computer. When you plug it in again. I hope this was really useful and be sure to subscribe leave comment like the video and thanks for watching.
